Rolling drum washing machine

Abstract

The invention provides a drum type washing machine which enables the setting of an even higher water level or an even lower water level by the users' intentions. The washing machine has a rotary drum 1 having the horizontal or diagonal center shaft of rotation, a water receiving tub 3 which is supported elastically in the body 9 of the washing machine and rotatably holds the rotary drum 1 therein, a feed water valve 14 for feeding water into the water receiving tub, a cloth quantity sensing means 30 for detecting the amount of washing within the rotary drum, a water level display part 22e which displays the water level set corresponding to the amount of washing sensed by the cloth quantity sensing means and a water alteration input setting switch 21j capable of altering the water level set. The water level alteration input setting switch is so arranged as to enable the setting of an even higher water level and moreover, an even lower water level as compared with the range of the water level set corresponding to the amount of washing detected by the cloth quantity sensing means, thereby relieving the anxiety about the washing performance felt by the users.

Description

technical field [0001] The invention relates to a washing machine which performs washing, rinsing and dehydration operations in a rotary drum whose rotation central axis is arranged in a horizontal direction or an inclined direction. Background technique [0002] In the existing washing machine, the rotary drum is rotatably supported on a horizontally arranged shaft. When laundry is put into the rotary drum and the washing operation is started, water is first added to the tub through the water inlet valve. Use the water level detection device to add water to a water level lower than the washing water level; after that, use the laundry volume detection device to detect the amount of laundry in the water-containing state, and then set the water level at the optimal washing water level according to the detection result ( One example thereof may refer to Japanese Patent Laid-Open No. 10-291). [0003] The above-mentioned existing device washes under the amount of water set acco...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned existing device washes under the amount of water set according to the amount of clothes detected by the clothes amount detection device, but in the drum type washing machine, the laundry is soaked into a high-concentration washing powder solution first, and then knocked. The advantage of the washing method is that it uses less water and can save water, but there is also such a potential dissatisfaction among users: the laundry is not easy to soak in the washing liquid during the washing process, and it does not look wet. Does not appear to be fully washed, rinsed, etc.

In addition, when the amount of laundry is very small, if the laundry is washed under the amount of water set according to the amount of laundry detected by the laundry amount detection device, the laundry is likely to float on the water, so the user also has the problem of not being able to complete the "first wash". Dissatisfaction with the normal laundry operation such as lifting and dropping, and it seems that the laundry cannot be really done
